Title (EN) CONTACT LENSES WITH BIFOCAL CHARACTERISTICS
(FR) LENTILLES DE CONTACT AYANT DES CARACTÉRISTIQUES BIFOCALES
Abstract:
(EN) A contact lens (318,400,500,600) may include a contact lens body (402), an exterior contact surface (322,404), and an annular bifocal surface (326,408). The contact lens (318,400,500,600) may be configured for use in a contact lens assembly (300) for laser-based ophthalmological surgical treatments. The exterior contact surface (322,404) may be on a first end of the contact lens body (402). The exterior contact surface (322,404) may be configured for direct physical contact with a cornea (102) of an eye (100) of a patient. The annular bifocal surface (326,408) may be on a second end of the contact lens body (402). The second end may be opposite the exterior contact surface (322,404). The annular bifocal surface (326,408) may include a central portion (347,412,502,602). The central portion (347,412,502,602) may include a first focal distance. The annular bifocal surface (326,408) may include an outer portion (349,414,504,604) that surrounds at least a portion of the central portion (347,412,502,602). The annular bifocal surface (326,408) may include a second focal distance.
(FR) Cette invention concerne une lentille de contact (318, 400, 500, 600) qui peut comprendre un corps (402) de lentille de contact, une surface de contact extérieure (322, 404) et une surface bifocale annulaire (326, 408). La lentille de contact (318, 400, 500, 600) peut être conçue pour une utilisation dans un ensemble lentille de contact (300) pour traitements chirurgicaux ophtalmologiques de type laser. La surface de contact extérieure (322, 404) peut être sur une première extrémité du corps (402) de lentille de contact et être conçue pour un contact physique direct avec la cornée (102) de l’œil (100) du patient. La surface bifocale annulaire (326, 408) peut être sur une seconde extrémité du corps (402) de lentille de contact, à l'opposé de la surface de contact extérieure (322, 404). La surface bifocale annulaire (326, 408) peut également comporter une partie centrale (347, 412, 502, 602) qui peut comprendre une première distance focale et une partie extérieure (349, 414, 504, 604) qui entoure au moins une partie de la partie centrale (347, 412, 502, 602). La surface bifocale annulaire (326, 408) peut comprendre une seconde distance focale.
